Powershell 给出 Get-Content : Exception of type 'System.OutOfMemoryException' was thrown

Question

我正在尝试使用以下命令在 powershell 中读取大小为 1 GB 的文件，

$data = Get-Content - 编码字节 $filepath

它抛出以下错误:获取内容:引发了“System.OutOfMemoryException”类型的异常。

搜索网络，发现运行下面的命令修复了它，但这对我不起作用。设置项 wsman:localhost\Shell\MaxMemoryPerShellMB 4096

Answer 1

默认 MaxMemoryPerShellMB = 1024MB如果你想读取大文件说 1GB 或更大，您需要设置 MaxMemoryPerShellMB。

使用下面的代码设置 MaxMemoryPerShellMB-

    function setpsmem
    {
          $winrmstatus = (get-service WinRM).Status
         if ($winrmstatus -eq 'Running')
    {
        $currentpsmem = (Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB).value
        if ($currentpsmem -le 4096)
        {            
            Set-Item WSMan:\localhost\Plugin\Microsoft.PowerShell\Quotas\MaxMemoryPerShellMB 4096
            Set-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB 4096
            Restart-Service winrm
            $currentmemory = (Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB).value
            Write-Host "Script assign $currentmemory[MB] of memory to PowerShell" -ForegroundColor Green
        } 
        else
        {
            $currentpsmem = (Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB) | Select-Object value
            Write-Host "Powrshell has $currentpsmem[MB] of memory." -ForegroundColor Green
        } 
    }
    else
    {
        Write-Host "WinRM services is not running on current host." -ForegroundColor Red
    }

} setpsmem

试一试。
